Trace width for toner transfer etching

Question asked by vagulus on Jun 29, 2018

I am making my first attempts at DIY PCB manufacture using toner transfer.  The default trace dimensions (KiCAD 4.0.7) are clearance = 0.2 mm, trace width 0.25mm.  Sadly this does not result in reliable traces on my copper - the trace lines are visibly fragmented, some don't transfer at all.


What dimensions have others found successful (without going overboard )?
